PMP 450 Planning Guide
Network Time Protocol (NTP)
The clock supplies accurate date and time information to the system. It can be set to run with or without a
connection to a network time server (NTP). It can be configured to display local time by setting the time zone
and daylight saving in the Time web page.
If an NTP server connection is available, the clock can be set to synchronize with the server time at regular
intervals.
PMP 450 devices may receive NTP data from a CMM3 or CMM4 module, an NTP server configured in the
system’s management network or a UGPS module.
The Time Zone option is configurable on the AP’s Time Configuration page, and may be used to offset the
received NTP time to match the operator’s local time zone. When set on the AP, the offset will be set for the
entire sector (SMs will be notified of the current Time Zone upon initial registration). If a Time Zone change is
applied, the SMs will be notified of the change in a best effort fashion, meaning some SMs may not pick up the
change until the next re-registration. Time Zone changes are noted in the Event Log of the AP and SM.
An AP which is receiving NTP date and time information from an NTP server or from a GPS synchronization
source may be used as an NTP server. Any client which has IP connectivity to the AP may request NTP date
and time information from the AP. No additional configuration (other than the AP receiving valid NTP data)
is required to use the AP as an NTP server.
Wireless Manager (WM)
Cambium Networks Wireless Manager 4.0 is recommended for managing PMP 450 networks. You can achieve
better uptime through better visibility of your network with the Cambium Wireless Manager. This network
management software tool offers breakthrough map-based visualization capabilities using embedded Google
maps, and combined with advanced configuration, provisioning, alerting and reporting features you can
control your entire outdoor wireless network including Mesh Wide Area Network, and Point-to-Multipoint and
Point-to-Point solutions as well as other SNMP enabled devices. With its powerful user interface you will not
only be able to control your network's access, distribution and backhaul layers, but you will also have visibility
to WLAN sites and be able to quickly launch indoor network management systems.
Some key features of Wireless Manager are:
• Template-Based Configuration: With Wireless Manager's user-defined templates you can accelerate the
process for the configuration of the devices you add to your network resulting in quicker and easier
deployments. The template-based functionality provides an automated way to configure large numbers of
network devices with just a few mouse clicks, and can be scheduled to occur at any time via Wireless
Manager's Task Scheduler.
• Ultralight Thin Client: With the growing mobile workforce it is important to have access to the status of
your network at any time. With Wireless Manager you can view the status and performance of your entire
wireless network via a compact web interface accessible by your smart phone.
• Map-Based Visualization: Wireless Manager overlays sophisticated real-time information about your
network elements onto building layouts and dynamic Google maps. Visuals can be scaled to view an entire
city or building or a specific area, floor or link.
